UNITED STATES PATENT OFFICE.

FRANKSTREIGH, OF JOLIET, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TOCHAMPION MACHINERY COMPANY, OF JOLIET, ILLINOIS, A CORPORATION OFILLINOIS.

T 0 all whom it may concern:

Be it known that I, FRANK STREIOH, a citizen of the United States,residing at Joliet, in the county of Will and State of Illinois, haveinvented certain new and useful Improvements in Long-LoafMoldii1gMachines, of which the following is a specification.

This invention relates to improvements in machines for molding dough inthe art of bread making and the especial object of the improvementswhich form the subject matter of this application for patent .is toprovide a machine of economical construction and of simple operationthat will transform an irregular shaped lump of dough into a cylindricformby first flattening the piece of dough and then coiling and rollingit into the shape desired.

In the accompanying drawing which forms a part of this application Ihave shown a preferred adaptation of my invention in the following viewsFigure 1 is a side elevation of a machine constructed according to myinvention; Fig. 2 is alongitudinal section of said machine;

3 is a side elevation taken at the side opposite from that shown in Fig.1, and Fig. 4 1s a top plan view of the machine.

Referring to the details of the drawing, A represents asuitablesupporting frame on which the various parts of the machine aremounted, journaled and secured.

13 represents a hopper in which are two chambers b 6 formed by verticalpartitions b, 1)", extending across the hopper and spaced from the endwalls of same as clearly shown in Fig. 2., To these partitions aresecured knives or scrapers b Arranged below the open bottom of thehopper and chambers b N, are two feed rollers C, O, the spindles ofwhich are suitably journaled in the frame of the machine. A spindle ofthe roller O is adjustably mounted in a block the position of which iscontrolled by the screw 0 in a well known manner, thus providing forregulating' the s ace between said rollers.

Journale in the frame in a plane below the rollers c, 0 are three otherrollers D, D and 6 The last named roller is adjustably and yieldinglyjournaled in a block e which is supported by coiled springs e and theblocks are vertically adjustable in their bearings by screws e Thespindle is journaled in blocks d which are horizontally adjustable inthe frame by means of screws (1 Coiled springs Specification of LettersPatent.

LONG-LOAF-MOLDING MACHINE.

Patented Nov. 19, 1907.

(2 press outwardly against the blocks (1 and thus hold the rollers Dunder tension.

Arranged to travel over the rollers D D and e, is an endless belt Ewhich extends substantially the full width of said rollers.

J ournaled in the frame at a point above the roller D is an idler rollerI the face of which is in contact with or near the surface of a drum Fwhich is mounted on a shaft f 2 jour naled in the extension of the frameof the machine. This drum has a segment out therefrom to form a recess fand the face of the drum is covered with a fabric f. Below the endlessbelt E and spaced therefrom a suitable distance, is a fabric coveredtable G having a downwardly extending portion 9 and an upwardlyextending portion at the opposite end, as 9 Pivoted on the upper edge ofthe hopper is a shutter b which projects into and partially covers thecenter chamber of the hopper B and extending rearwardly from the shutterb is an arm I) which is arranged in the path of a pin projecting fromone side of the drum F. The weight of the arm. I) is sul'licicnt tocounterbalance the weight of the shutter b and a lump of dough placed onsuch shutter.

On the shaft 7L1 are mounted tight and loose pulleys II adapted to bedriven from any suitable power. On the opposite end. of this shaft is apinion 7L2 which meshes with the pinion c secured on one end of theshaft of the roller 0 On the opposite end of the shaft of said roller isa'pinion c which meshes with the pinion c mounted on one end of theshaft 0. On the opposite end of the shaft 0 is a sprocket gear a onwhich travels a chain c which also travels on a sprocket d on one end ofthe shaft (1. On the end of the shaft 0 adjacent to the pinion c, is asprocket wheel 0 on which is mounted a chain c which travels over asprocket 11 se cured on the spindle of the roller 1. On the shaft f 2 atone side of the drum is mounted a belt pulley f over which travels acrossed belt f which also travels over the pulley c on the shaft orspindle of the roller 0 The operation of a machine constructedsubstantially as described will be as follows Upon power being appliedto the tight pulley H, the shaft 7L1 will be driven thus rotating thepinion-h, pinion c pulley thus (lllVlll the belt f, pulley f and thedrum F. The shaft 011 which the pinion is mounted being driven, in turnrotates the pinion c and pinion c on the shaft 0 The sprocket c andchain driven by the shaft 0 will in turn drive the sprocket i on thespindle of the roller I. The sprocket a on v the opposite end of theshaft 0 being rotated by said shaft, will, through the chain c, drivethe sprocket d on the shaft (Z and thus rotate the roller D secured onsaid last named shaft. The rotation of the drumF through the pin f willat intervals trip the arm 17* and thus depress the shutter b and permita lump of dough placed on said shutter by the operator to drop throughthe chute between the rollers C, C and the rotation of said rollers willdraw the lump downwardly between same upon the endless belt E by whichit will be carried under the roller C thereby flattening said piece ofdough so that when it reaches the drum F, (which is rotating in thedirection indicated by the arrow in Fig. .2) the forward edge of thepiece of dough will come in frictional contact with the surface of thedrum and will be turned upwardly until it meets the under surface of theroller I, which is rotating in the direction indicated by the arrow, andthus the lump of dough will be coiled into a cylindrical form indicatedin said figure and will be rotated by the combined action of said drumand roller until the surface of the dough is smooth. When the drunrinthe course of its rotation, presents the cutaway portion f opposite thelump of dough, the opening thereby presented will permit the belt E tocarry the dough downwardly upon the table G and along the surface ofsaid table until it reaches the downwardly inclined portion g when thedough cylinder thus formed will roll by gravity to position to beremoved by the operator.

It will be apparent that through the adjustability of the idler roller 6the extent of the flattening of the lump of dough between the endlessbelt E and the roller 0 may be fully controlled.

It will also be apparent that the extent of the frictional contactbetween the surface of the drum F and the dough will largelydeterminethe degree of smoothness of the said piece of dough. Inoperating the machine, if it be desired to have the entire operativesurface of the drum frictionally engage the piece of dough, the operatorwill so adjust the parts that when the dough reaches the drum it will beengaged at the point 90, and if less frictional contact is desiredit'will begin at the points y or 2. This is an important feature in theoperation of this machine in view of the fact that dough varies in itsdensity, some batches requiring more Working or molding than others. Inthe manufacture of my machine the drum will be of such diameter as toprovide sufficient frictional contact for the quality of dough re- It isobvious that a plurality ofsegments I may be removed fromthe drum thusincreasing the number of recesses f and providing for a greater numberof lumps of dough passing the drum at these points. The distance betweenthe belt E and the table G will be such as to provide contact with thecylindrical lump of dough and thus feed said lump forward and at thesame time tighten the coil formed by the drum, belt and roller I, abovedescribed, so that when the lump is removed it will be thoroughly moldedand have a smooth exterior.

. Having thus described my invention what.

I claim, is

- i 5. Ina dough molding machine, a hopper,
